I've just come across a 1955 Tudor Submariner. Ref: 7923 for sale at a specialist auction house in Wiltshire, England.
It's a manual wind model on a non-Tudor bracelet, with what appears to be some nice provenance.
Estimate £30-50,000
It's LOT 64 at GARDINER HOULGATE, Corsham, Wiltsshire. UK. SN13 9SW.
I have no vested interest in this company or the watch, just thought someone here, might be interested.
